Ok Owley.What is the reason for a warthogs' tail standing upright when it is running?Now, think a bit out of the box (my answer to Sleepyowl21's cheetah question will tell you in which direction this is going)Then more on a serious note:When dung beetles roll their dung balls all over the place, they sometimes get on top of them and make a few turns before they carry on rolling them away. Whay do they do that?

Question1When they run through the grass they almost closes their eyes for the grass seeds and stuff. The skin on their back is so tight that when the eyes closes the tail get pull up by the tight skin. Something like that in English

Question2They get on top to make sure they go in the right direction, that their partner is still on the ball and that no other male is trying to steal the ball or his mate.

[quote][/quote]I agree, 300km is very far (even travelling in a car), however, if they are capable of this , it could be because there is a constantflow of vultures in the same direction . . that is; the one in the front is seen by the next one in the que, and so on. (Actually got NO idea)

Vultures do travel far to a carcass. The ones nearest to the carcass go down. Then the next ones a bit further spot them and then fly in and so the ripple continues. 300km might be far but the ripple could continue to them but I think they might arrive a bit late at the party.The distance was just to get sight and smell out of the way.
